The various web s or llanges 2l, ont the operating` mechanism and a section of at their upper ends, are disposed laterally the car, showing a modification of the or prei'erably connected bynieans of the in- 109 mounting, tegral plate portion 22 haying a slope simi- MY invention relates more @Specially to lar to that ot the slope-sheet l1 of the car the mounting of the hand brake gear mechbottom so to extend parallel and. flush "o anism on the well known type of hopper car, therewith; the plate portion 22 being riveted wherein the ends of the car consist of the as shown at 28 or otherwise firmly secured 305 vertically disposed wall, a portion Whereto the slope sheet ll of the car: The gearing' of is shown at 10 and the inwardly and of the hand operated mechanism .may beoif downwardly sloping bottom a portion being any suitable type which may provide a quick take-up of slack in the brake' operating chain while also successively providing a. suitable multiplication of power for the proper operation of the brakes; a portion of the driven element or gearing being shown at 2d (Figure l) which is secured to the upper end of a shaft or brake staff section 25, which at its lower end is preferably provided with a suitable cha-in winding` element or drum at 2G to receive and wind up the chain 27 which is attached to the air brake lever lS.

The lower end of the brake staff section 25 is journaled in a skeleton member or frame 28 having a top portion 29 and a bottom portion 30 connected by or preferably formed integral with the side portions 3l to provide a suit-able mounting and open-sided housing for the drum Q6 or the chain 27 when the latter is wound up during brake application. The top portion 29 and the bottom portion 30 are each provided with aligned openings in which the brake staff section 25 is journaled. The top and bottom portions of the member QS are both ei:- tended outwardly toward the end of the car so as to permit said portions to be suitably connected tothe end sill l5 on the inner side thereof, thus permitting the brake staff section 25 to be if'ertica-lly disposed and the axis of the chain drum 26 aligned with the axis of the driven gear 24 of the gearing. The extended top portion 29 of the bracket, in the particular exemplification, is formed to extend beneath and flush with the upper flange. 32 o-f the end sill 15, and is firmly secured thereto by means of rivets as shown at 33; while the bottom portion 30 is shown ext-ended beneath and flush with the lower flange of the end sill; the immediate outer end of the extended bottompreferably being upturned or flanged as at 931i to lap the outer side of the end sill l5 and thereby provide additional anchorage for the housing or bracket 28 adapted to resist the pulling strains to which it is subjected during the application of the brake mechanism and which are thus transmitted to the car underframe. The bottom portion SO is preferably riveted at 35 to the lower flange of the end sill l5. rlfhe'flange or upstanding portion 3l on' the bottom of the housing is provided where the greatest pulling strains are encountered; the flange together with the rivets being suihcient to resist the strains resulting during operation of the hand brakes.

As the brake staff, which receives the hand wheel (not shown) must be located to the outside of the car end wall l0, a portion of the gear housing 2O is disposed beyond the end of the car without, however, extending beyond the vertical plane of the striking block or castings (not shown) of the car and therefore in keeping with the safety appliance rules. rlhis forward end of the gear housing 2O is provided with the drive gearing outlined in dotted lines at 36 and the top is apertured to receive the brake staff section 37, to the upper1 end whereof the usual hand wheel or hand leve-r is secured for operation of the hand brake mechanism. y

In Figure 4, I show a modified form and method of mounting the gear housing which may be of the same general construction as the gear housing 20 shown in Figure l. In

. this construction the top of the housing 38 is provided with the somewhat rearwardly sloping webs or flanges 39, of suitable number arranged in spaced relation transv rsely of the housing, like in Figure l; the webs or flanges 39, like the webs or flanges 2l, being preferably formed integral. with the gear housing to provide a rigid unitary structure which may therefore be readily assembled and put into place. rlhe webs or flanges in the construction shown in Figures at what may be termed the outer or forward side of the housing, are extended upwardly beyond the plane of the slope sheet ll of the car and formed to extend parallel, as shown at lO, with the vertically disposed end wall 10. The webs or flanges 39 and their eX- tended portions 40, like in the construction shown in Figure l at their tops, are united by a plate or preferably formed integral with a transversely disposed web portion Lll. The vertical webs or flanges and the plate portion are made to conform with the obtuse angle described at the juncture of the end wall 10 and the slope sheet or bottom ll to permit the plate portion 4l to extend flush with the end wall portion lO as well as with the slope sheet l1 and to be firmly secured thereto as by means of the rivets e2.

lVith this construction, it is apparent that a very firm and rigid mounting is provided while at the saine time the gear housing is maintained rearward of the vertical plane of the striking block or casting at the ends of the car center sills and thus complying with the safety appliance rules. lilith the construction shown in Figure l, like that shown in Figure l, the brake staff comprises the two sections Q5 and 37; the former extending from the driven gear Zei to the bracket which may be secured to the end sill as shown in Figure l, where the staff section is generally provided with a chain drum as shown in Figure l; while the upper staff section 37 is disposed forward of and parallel with the end wall of the car and extends to the top of the car where it is provided with the usual hand wneel or lever (not shown).

In hopper cars of the type in question where the hand brake mechanism is operated from the top of the car, it has been usual to mount the gear mechanism and housing ad- `jacent to or on the end sill of the car, with the ygearing operated by means of a oontinu- Mii] l Ui) lll) all

ous single brake staff extending from the end sill toward the top of the car. In constructions of that type considerable difficulty has been encountered because the gear housing extends too far forward of the end sill, while any attempt to overcome this trouble by moving the gear housing rearward on the end sill, positions the mechanism where the gearing interferes with a proper operation of the air brake lever 18. lVith my improved construction and method of mounting', it is apparent tha-t these ditiiculties have been entirely eliminated, as the housing will not extend beyond the point required by the safety appliance rules and the large driven gear is located where it can in no way interfere with the operation of the air brake lever 18. Furthermore, by employing the comparatively short staff sections, they are better able to withstand the torsional strains than is the case with a continuous long brake staff reaching from the top of the car to gearing located on or adjacent to the end sill For the sake of lightness, the upwardly disposed portions of the housings disclosed in Figures l and 4 are shown in the form of gussetdike flanges or webs and the upper ends of these flanges are preferably united by a continuous transverse web or plate which enable the housing to be more readily attached to the end of the hopper car.

I have shown what I believe to be the simplest and best embodiments of my invention; having described them in terms employed merely as termsof description and notas terms of limitation, as structural modilications are possible and may be made with.- out, however, departing from the spirit of my invention.
